CARPET STRETCHER AND TACKER.

SPECIFICATON forming part of Letters Patent N. 394,934, dated December 18, 1888,

Application filed November 17, 1887. Serial No. 255,399. (No model.)

T0 all 'Lu/"wm may concern.-

down into this tube the sections will be forced Beit known that I, HENRY i3. IITNER, a apart at the bottom, and also that when the citizen ot' the United btates, residing at Ila Porte, in the county ot' 'La Porte and State ot' Indiana, have invented certain new and useful Improvements in Carpet Stretchers and vrPackers; and I do declare the following' to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to carpet-stretchers; and it consists in the novel construction hereinafter specified, whereby a carpet may be readily and etl'ectively stretched to the 'position desired and the same automatically tacked to the floor.

The invention will be fully understood trom the following description and claims when taken in connection with the annexed drawings, in which- Figure l is a perspective view of my improved carpet stretcher and tacker. Fig. 2 is a sectional view of the same, taken on the line 0cm ot' Fig. l.; and Fig. il detail view.

Referrin tothe said drawin by letter, A indicates a block lnet'erably provided with a leatherbott om, u, and a t'ront metallicplate, c. Passing through the bottom u and into the block is a series of teeth, b, arranged in diagonal positions, as shown in Fig. l of the drawings.

indicates a handle, which. is rigidly attached to the rcar eml ol' the block A in any suitable manner.

C represents a trip-liannner, the rear end of which is pivoted :in the brackets or ears I). Said brackets are rigidly secured to the upper face ot the block A. A spring is coiled around thepivot-pin or shaft of the hammer and out` side the upright portions ol the brackets I), both to the right and leit't of the hammer, as shown on Fig. l, the middle pori ion, j', resting against the curved rear end ot' t-he hammer, as also shown on Fig. l.

G represents a tube, preferably formed of two sections arranged in the front end o t' block A and with projecting ears at their tops, which are united by means ot coiled springs h.

It is obvious that when the hammer passes is a sectional hammer is withdrawn the spring 7L will retract the sections so as to leave a small opening at the extreme lower point of the tube.

G represents a tulmlar tack-holder, which is preferably arranged in an inclined position with its rear end resting in a bracket, n, attached to the handle l$,'and with its lower t end supported in a similar bracket, n', at-

tached to the block A, as shown. The eX- treme lower end ot' this tube rests upon or over the top ot the under section of the tube G, so that when the hammer is withdrawn a tack will fall by gravity into said tube.

K represents a bent operating-lever pivoted to the handle B, near the lower end thereof, in a suitable bearing-lnacket, p, and extending upward to a pointconvenient for the hand to grasp and use. It will be seen that the said operating-lever K is bent into substantially the form ot an obtuse angle, the.

lower straight portion of the vsaid lever being bent at a slight distance in ilront of the said angle (marked s) to form a trans\f'erse arm, q,

which is adapted to work in the bearing or socket p, and thus I provide a strong pivotal connection between the a'li'oresaid lever and the handle B. The lower portion ot` this lever rests normally in a notch, n, formed in the raised standard o, which is attached to the upper curved portion of thetrip-hammer. By pressing the upper end ol' the operating-lever downward the hammer is raised from tube G, and the lever slides along in notch nv until it reaches the shoulder y] on said lever, when it becomes disengaged and the hammer drops, driving a tack into the tloor, which in the meantime has fallen from tube G into tube G.

The operation of my invention is as follows: The device is placed in position upon the carpet with the teeth b engaging the same. The carpet is then stretched to the desired point, whereupon the hammer C is elevated a slight distancev by the operatinglever K, and a tack iis dropped from the tube G into the spring-actuated sectional tube G, where it will be held in an upright position by the springs 7i, which at'ter the lower end ol the hammer has been removed from the said tube G will cause the lower ends of the sections of the latter to come together and IOO clinch the tack and hold it in a position to be driven into the carpet by the descending hammer, after which the hammer is raised to its highest point until the notch in the arm o reaches the curved shoulder y, formed at the end of a track, Ar, on the lower straight portion oli' the lever K. The handle 0i' the said lever l is then depressed a slight distance, which action releases the notch not the arm o from the shoulder vy, and thus trips the hammer, the latter then descending with greatforee upon the tack, which has in the meantime dropped trom the feediiig-tube into the spiingactuated sectional tube G by the operator. lt will be clearlT understood that after the hammer has been tripped the notch in the arm 0, formed on the hammer,

will be disengaged from the straight engaging track portion ot' the operating-lever K. Now, as the said lever is capable ot' lateral movement in the bearing or socket p, bet'ore described, it is 01115v necessary to shift the end of the said lever into engagement with the j the said aperture to grip a tack, the inclined notch `n and the device is ready to be again operated in the manner hereinlietore described.

The operation ol' my invention will be very readily understood from the foregoing description when taken in connection with the annexed drawings.

It Should be here observed that this tube is not a reservoir, but is intended to receive but one tack at a time, the same being fed by the operator before each blow oi' the hammer.

Having described m v invention, what. I claim isl. A carpet stretcher and tackcr having the base A and the handle B, both being provided with supporting-brackets, in combination with the tack-feeding tube G and operating-lever K, the latter having the shoulder f l/ to engage with the notch n oi' the trip-hammer, the triphammer, the transverse pivotal connecting-arm q of the dischargetube formed with spriiig-actuated sections for clinehing and holding the tack in position to be driven by the hammer, sllbstantially as described.

9. The combination, with the base having the spriiig-actuated jaws to receive and hold a tack, of a springaotilated hammer having a lug, o, shouldered on one side and the operating-lever bent outwardly, as shown, and having the straight portion fr to engage the lug on the hammer, substantially as specified.

Il. The improved carpet stretcher and tacker herein described, consisting, essentially, of the base-block having prongs or teeth and a vertical aperti'lre in its forward end, the spring-actuated plates arranged :in

feed-tube leading to the said aperture, the curved spring-actuated hammer having the shouldered lug o, and the pivoted or hinged operati ng-lever curved, as shown, and having the straight engaging portion provided with a tripping-shoulder, 51S 1U, substantially as specified.

In testimonyv whereof I :'Lt'tix my signature in presence of two witnesses.
